Author Notes

Montauk swordfish layered with butter; Merrill's summer squash with chili, mint and toasted almonds; some good bread and a big salad--can you think of a better dinner before vacation? We finished with Kelsey's chocolate cake and coffee--and now we're packing for family reunion at the beach. It's a great life! - drbabs —drbabs

Test Kitchen Notes

Brining the fish made it ultra juicy and the compound butter was very tasty. - Cecilia —The Editors

What You'll Need
  • 1 cup warm water
  • 1 TB kosher salt
  • ½ cup (1 stick) butter, room temperature
  • 1 tsp minced garlic
  • 1 TB lemon zest (zest of 1 lemon)
  • 1 TB minced parsley
  • 1/2 tsp red pepper flakes
  • 1 TB Worcestershire sauce
  • ½ tsp kosher salt
  • 1 1-lb swordfish steak
  • olive oil
  • Fresh ground black pepper
  • Flaky sea salt
  1. Early in the day, mix 1 TB kosher salt into a cup of warm water. Stir well to dissolve. Refrigerate till cold.
  2. Mix minced garlic, lemon zest, parsley, red pepper flakes and Worcestershire sauce into softened butter—mix well. Put into ramekin and refrigerate.
  3. About 1/2 hour before cooking, put the swordfish into the brine for 10 minutes, turning once after 5 minutes. Rinse fish well and dry. Let fish come to room temperature and start grill. Take compound butter out of refrigerator and let it come to room temperature as well.
  4. Rub swordfish steak with olive oil and sprinkle generously with fresh ground black pepper. Grill fish over direct heat until just cooked through, about 5 minutes per side (depending on thickness). Let fish rest, covered, for 5 minutes. Serve with compound butter layered on top and a sprinkling of flaky sea salt.
  5. (The butter is amazing on a baguette, too!)

This sounds really good. I was thinking of putting it on Tuna steak, I don't care for Tuna but its my boyfriends favorite fish so I sometimes indulge him. The compound butter sounds good I am hoping it will add the flavor I need on the tuna ;) Thanks for this one.

Great recipe! Thanks for letting me know. I missed this one before.
Sagegreen August 22, 2010
I think I only look at recipes with photos, which is probably why I missed this!

Thanks--I was having trouble with my camera when I made this--now I use my phone and it's better than my camera...sad.

Really lovely; I have to get into compound butters, and this seems like the perfect way to start now that I'm obsessed with swordfish again

I need to set up a potluck in Chicago so I won't be so jealous!
drbabs July 15, 2010
Thanks so much! I'd love to do a potluck, too-- I live on long Island--will have to glom onto the next one in NY!!

Compound butter is one of my favorite ways to dress up simply grilled meats or fish - yours sounds great!
drbabs July 14, 2010
Thanks--it's one of mine, too!

Dr Babs you really need to come on down here for our next potluck (fall maybe?) so we can all cook together!
drbabs July 14, 2010
That sounds like fun! We usually come down in fall or winter--I'll let you know.

Sounds delicious! I'll make this tonight and pretend that we're going on vacation to the beach tomorrow!
